I took a piece 3/4" plywood, and cut it approximately 13'' X 3.5"...then cut a slot 3.5" X 1/2" in one end to make a lever to twist the trunk spring into place. I also screwed a small strap of steel across the 1/2" slot to keep the wood from splitting apart. You still have to pry the end of the spring with a screw driver or similar tool until you line up the spring with your desired slot position. My camera is dead...otherwise I would have sent you a pic.
